  Log Message:
  -----------
  Add codegen for llvm log2/log10 elementwise builtins

Add codegen for llvm log2 / log10 elementwise builtin
The log2/log10 elementwise builtin is necessary for HLSL codegen.
Tests were added to make sure that the expected errors are encountered when these functions are given inputs of incompatible types.
The new builtins are restricted to floating point types only.
